DM shows the almost final version of his presentation on the eta_c channel. The comparison STT vs TPC is done using the old STT data on the GRID and the new TPC data. The analysis require at least on hit for STT. The STT efficiency is now reduced by few %.\
There are some inconsistencies for the entries of the histograms. Some histograms still need to be updated. DM will check everything before the review.\
\
GB says that he checked that the new version of the STT pattern recognition is working well. Therefore, the problems observed by DM on the new STT data cannot be due to it. Nevertheless, the reason for the reduced efficiency in the new STT data is not know. For the review the old data will be presented.\
\
MM shows STT and TPC performance for the Psi(3770) benchmark channel. The details of the analysis are presented and everybody agreed on the used procedure. The final presentation including fits and resolutions will be available only after the week-end.\
\
EF shows the almost final version of the multi-pion final channel analysis. Even here the requirement to have at least one hist on the STT has been introduced.\
\
GB asked to EF to try on the multipoint final state the new version of the STT pattern recognition that includes event cleaning. Due to lack of time the results will not be presented at the review.\
\
The GRID has been shutdown. Nevertheless, the data have been copied in Groningen and further analyses are still possible there.\
\
FB shows the results of the new single track events analysis. Now muon have been generated and it is possible a direct comparison with STT results. Nevertheless, for the momentum resolution, STT provide only that combined with the MVD. \
TPC is able to show also the TPC alone resolution. More results concerning event mixing, detector calibration influence and secondary vertices determination will be ready only after the week-end.\
\
Regarding the possibility to perform a STT pattern recognition without a precise T0, GB and PW are working on this issue.\
Nothing is already available to be presented.\
\
LS requests that all the material that will be presented at the review have to be first approved by the tracking group.\
All the presentations should be available on Monday, Aug. 8, before lunch.\
\
On Aug. 8 the executive board of PANDA, with also BK and JR, will meet to define the strategy and the indications we would like to ask to the reviewers.\
